Peyton Manning has regained his NFL record for touchdown passes with 51 and the Denver Broncos have clinched the AFC West.

Manning threw for 400 yards and four touchdowns, including three in the fourth quarter to surpass the 50 TD passes Tom Brady threw in 2007. Manning led the Broncos (12-3) to a 37-13 win over the Texans (2-13) yesterday that extended Houston's franchise-record skid to 13 games.

Manning did it on a 25-yard pass to Julius Thomas with 4:28 remaining. Just 2 ½ minutes earlier, he tied the mark with a 20-yard pass to Eric Decker.

He entered the game with 47 and his first touchdown came on a 36-yard pass to Demaryius Thomas in the second quarter, and the second one was a 10-yard throw to Decker earlier in the fourth period.
